between the ends of the inner and outer members 1 and 2 will o erate to form a suction in the space 6, t ereby drawing elements of the tire extinguishin chemical from the hopper to the space 6, from which latter the chemical will be mixed with the Water and discharged therewith from the outer end of the nozzle. It will of course e understood that by providing the inner member 2 with a restricted outer passage and a relatively large lnner passage the nozzle will operate on the discharge of Water therefrom to cause a quantity of the Water to be discharged into the perforated sprayer 9 b way of the leg 10. In this manner the salts or powdered iire extingulshing chemicals will be saturated with To all whom it may concern:

Be it known that I, RICHARD PA'rrIN, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Fire-Extlnguishin Nozzles, of which the following is a speci cation.

This invention relates to fire extinguishing nozzles, and has for an object to provide a nozzle adapted for the reception of a fire cxti'nguisl'iing chemical which is automatically forced from the nozzle on the effective discharge of the water.

In the drawing, forming a portion of this reference .indicate simllar parts 1n the sevdirectly into the space 6 for the purpose hereinbefore specified.

While the nozzle described herein is particularly intended to be used where it is desired to dispharge the chemical with the Water, it will of course be understood that I do not limit myself to such use, as it is obvious that the nozzle can be used as an ordinary nozzle without discharging a chemical solution with the water.

claim l. A tire extinguishing nozzle comprising inner and outer spaced tubes, each of said tubes being formed with a relatively large inner portion and a restricted outer portion,

chemical discharging space 6 entirely around the inner member 2.

hopper 7 is supported by the outer member 1, the reduced end 8 of the hopper Jitted to and disposed above the passage in the member 1 and arranged thereinso that therewithin and havlncr a leg portlon eX- ing space 6. The hopper is designed for the reception of a owdered tire extinguishing chemical, pretrably salt, and in view thereof, I provide the hopper 7 with a perforated sprayer 9 havin a leg portion 10 which extends downwar ly at one side of the hopper within the same and which opens directly into the inner member 2 substantially at the inner end of the nozzle.

The outer end of the member 1 extends to receive water on the flow of the same considerably beyond the outer reduced end through the inner tube. of the inner member 2 so that when the wa- 3. fire extinguishing nozzle comprisin 110 ter is discharged from the small end of the inner and outer tubes, the said tubes eac inner member its passage in the space 1l being of an outwardly decreasing diameter,

wardly decreasing diameter, the said tubes 10o ried by the hopper and having a water ina hop er carried by the outer tube, the said tubes eing spaced from each other to form an intervening chemical receivin space for receiving the chemical from the opper, the said hop er being in open communication with sind) space, and a sprayer carried by the hopper and having an intake portion extending downwardly into the inner tube and disposed adjacent to the large end of the said tube so that a part of the water under 10 pressure when discharging through the tube will be directed to the sald sprayer.

In testimon whereof I aix my signature in presence ci two witnesses.
